Abstract

A lubricating grease having a high dropping point, good stability against oxidation and long life contains a thickener comprising essentially the three components: lithium soap of C12-24 hydroxy fatty acid; lithium phosphate salt produced from phosphoric or phosphorous acid ester and dilithium borate. The amounts of hydroxy fatty acid and phosphoric or phosphorous acid ester are 3-100 parts by weight and 0.05-15 parts by weight per part by weight of boric acid respectively.

Description

【発明の詳細な説明】 産業上の利用分野 本発明は、高い滴点、優れた酸化安定性、長い潤滑寿命

物に関するものである。TECHNICAL FIELD The present invention relates to a high quality lithium complex grease composition having a high dropping point, excellent oxidative stability and a long lubricating life.

従来技術 リチウム石けんグリースは耐熱性、耐水性およびあらゆ
るタイプの潤滑油基剤への石けんの分散が容易であるた
め市場において５０％以上のシエアを有している。Prior Art Lithium soap grease has over 50% siaer in the market due to its heat resistance, water resistance and easy dispersion of soap in all types of lubricant bases.

Ｃ12−Ｃ24オキシ脂肪酸リチウム石けんとほう酸モノリ
チウム塩とを含むリチウム石けんグリースが教示されて
いる。As a conventionally known technique, Japanese Patent Publication No. 54-2205 teaches a lithium soap grease containing a C 12 -C 24 oxyfatty acid lithium soap and a monolithium borate salt.

また、特公昭５７−47235 号公報には従来公知のほう酸

オキシステアリン酸とほう酸ジリチウムとの組合せは高
滴点グリースが生成しないことが教示されている。Further, Japanese Patent Publication No. 57-47235 discloses a known complex grease containing lithium borate.
It is described that a high dropping point grease (482 ° F or higher) can be produced from lithium hydroxystearate soap and monolithium borate. The combination of 12-hydroxyoxystearic acid and dilithium borate is a high dropping point grease. Is not generated.

このグリースは滴点（４８４゜F）およびちよう度（２
３１）共に上記の過酷な運転条件下では十分に満足でき
るものではなかつた。This grease has a dropping point (484 ° F) and a fineness (2
31) Both were not sufficiently satisfactory under the above-mentioned severe operating conditions.

また、特開昭５７−212298号公報にはジカルボン酸のリ
チウム塩とリン酸、亜リン酸のリチウム塩とを含む高滴
点グリースが教示されているが、ちよう度（２７４）は
従来公知のグリースとほゞ同程度であつた。Further, JP-A-57-212298 teaches a high dropping point grease containing a lithium salt of dicarboxylic acid and a lithium salt of phosphoric acid and phosphorous acid, but the degree of twist (274) is conventionally known. It was about the same as the grease of.

発明の解決しようとする問題点 近年、機械、装置の高温下における運転あるいは高速、
高荷重下での運転などによりグリースの使用条件が過酷
になつてきた。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In recent years, operation of machines and devices under high temperature or high speed
The usage conditions of grease have become severe due to operation under high load.

従つて、通常のリチウムグリースの性能では不足する用
途が多くなっており、より高温に耐え、長寿命のグリー
スが要望されている。Therefore, there are many applications in which the performance of ordinary lithium grease is insufficient, and there is a demand for grease that can withstand higher temperatures and has a long life.

通常のリチウムグリースは連続使用可能限界温度は１２
０℃ないし１３０℃であり、１５０℃以上の高温になる
と酸化劣化によるミセルの破壊、グリースの軟化、離油
度増加等によりグリースの潤滑性が失われる。Ordinary lithium grease has a continuous usable temperature limit of 12
The temperature is 0 ° C. to 130 ° C. At high temperatures of 150 ° C. or higher, the lubricity of grease is lost due to destruction of micelles due to oxidative deterioration, softening of grease, increase in oil separation, and the like.

現在の自動車、電動機、鉄鋼機械、その他諸工業機械、
設備におけるグリース潤滑部分では使用温度が１５０℃
以上となる例が多くすぐれた高温用グリースが要望され
ている。Current automobiles, electric motors, steel machines, other industrial machines,
The operating temperature is 150 ° C in the grease lubrication part of the equipment.
There are many demands for excellent high-temperature grease.

滑不良を起す可能性を有する欠点がある。For example, in a vehicle equipped with a disc brake, there is a risk that the wheel bearing grease will be exposed to a temperature of 150 to 200 ° C due to the frictional heat generated by the brake operation. However, there is a drawback that deterioration due to oxidation or rapid deterioration may cause poor lubrication.
